CUTTINGH'PLHERS.

SDJCIFECATIN forming part of Letters Patent No. Sil-1,136, dated IJay4:,- 1886.

Application filed February 3, 1835. Serial No. 190,696. (No ni'idcl.)

.T aZZ whom t may concern.-

Be it known that I, Bonner C. ELLnion, a citizen ofthe United States,residing at Southington, in the county of Hartford, State ofConnecticut, have invented certain new and useful Improvements inCutting-Pliers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to that class of tools, commonly known as cuttingpliers7 or nippers,7 which are used for cutting or severing wire, rods,and the like.

The object of my invention is to produce a tool of this kind which willbe of simple and I inexpensive construction, and in which the device foroperating the cutting-jaws may readilyT be adjusted to determine thenearness to which the jaws shall approach each other in the cutting ornipping operation.

My invention consists,cssentially,in providing a tool having a cuttingor nippingjaw or jaws pivoted in a head or frame,with a sliding pinoperated by a pivoted handle or lever to force the pin inward betweenlever-arms of the cutting-jaws, to cause the cutting-edges of said jawsto come together, the said pin being provided witli an adjustable gageto limit its inward movement, and consequently enabling the user todetermine the nearness to which the cutting-edges shall approach eachother, this gage, by reason of its adjustability, also permittingcompensation for wear of the cutting-edges.

In the accompanying drawings, in the different figures of which likeletters of reference designate corresponding parts, Figure l illustratesa side View of a tool made in accordance with my invention; Fig. 2, acentral longitudinal section taken onaplane at right angles to thedirection of the cutting-edges, Fig. l. Fig. 3 is a view in edgeelevation of the cutting-jaw.

The letter A designates the head or frame of the tool, one end of whichis provided with a fixed handle, a, at one side and a movable handle orlever', b, pivoted upon a pin, c, at the opposite side. This pivotedhandle or lever Z1 is provided with a shoulder, d, for a purpose to behereinafter explained. In the other end of the head or frame A are twojaws, B, pivoted upon pins e in such position that their cutting-edgeswill come together edge to edge. lach of these jaws may have thatportion which is provided with the cutting-edge widened or enlarged toafford a longer cuttingedge, as clearly indicated in Fig. 3. The innerendsof the jaws are enlarged or provided with shoulders j', for thepurpose presently to be explained.

The head or frame is provided with a longitudinal hole or opening, g,through which a movable rod or pin, 7L, passes. This pin h has itsinnerend-that is, that end which rests between t-hc shoulders f on thecutting-jaws-n beveled like a wedge, or tapered, and its outer endscrew-threaded and provided with an internally-tlneaded nut, t', Iittingon said screwthreaded end of the rod or pin. This :nut is adjustable andserves asra gage to limit the inward movement of the pin or rod. Theshoulder Z on the pivoted handle or lever b acts, when properly operatedin the hand, against the outer end of the pin h to force said pin inwardwhen required, and the nut i, by coming into contact with the end of thehead, serves to limit the inward movement of the pin. The opposite sidesofthe wedge-shaped or tapering end of the pin bear/ against theshoulders j' on the pivoted cutting-jaws, so that when said pin isforced inward the inner ends of the jaws are thrown outward and theircntting-edges together. A bent spring, j, is placed between the jaws, tobear against them in such manner as to keep the cutting-edges separatedwhen not in use.

A small opening, 7c, may be provided in the side of thetool, to enablethe user to see the tapered or wedge-shaped end of the pin or theinterior of the head or frame, or to remove particles interfering withthe operation of the device.

I wish it clearlyT to be understood that I do not confine myself to theexact forni or configuration of parts illustrated, as they may obviouslybe changed without departing from the scope of my invention, whichresides principally in the movable pin 71., provided with the adjustablegage.

It is obvious that one of the cutting-jaws may be fixed.

My invention may also'be used in that class IOO of tools known aspinchers, in which the jaws are not to cut but simply to hold an object.u

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

l. In cutting-pliers or thelike, the movable pin h,for operating thejaws, provided with an adjustable gage, t', substantially as described.

2. TheheadAand cuttingjaws pivoted therein, combined with the pin It,for operating said jaws, provided with the adjustable gage,substantially as described.

3. The combination of the head or frame, cuttingjaws pivoted therein,the pin 7i, provided with the adjustable gage t', and an operatinghandle 0r lever pivoted in said frame or head, having a shoulder to actagainst the pin h, substantially as described.

4. In cutting-pliers, the pin 71, having the wedge-shaped or taperingend to operate the cutting-j aws, and provided with the adj ust-ablegage t', for the purpose set forth.

5. The herein-described improvedveuttingpliers, comprising a head orframe provided at one end with a iixed and a pivoted handle, a pair ofcutting or nipping jaws pivoted in the other end, a spring actingagainst said jaws to hold them apart, and a pin having a wedgeshaped ortapering end, movable between the jaws at one side of their pivots toclose them at their other side, and an adjustable gage, z', upon saidpin to limit its movement, to determine the nearness to which the jawsshall approach each other at their cutting or nipping ends,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
